The other poster roundly dispatched your comment about using a “crypto credit card” so I’ll defer commentary on that.

On the others: the crux of my argument was adoption and usage, with the implication that cryptocurrency was better for the usecase than traditional methods. Of course you can shoehorn a blockchain or “the chain” into any usecase, just like I can use C to write a frontend service, but it doesn’t make sense because C isn’t the best or even a good tool for the job. I can buy bananas and put them on the blockchain, doesn’t mean there is any reason to do so aside from pumping up any cryptocurrency holdings I might have, perhaps BananaCoin or BananaICO or Gorilla NFTs, which I just invented right now.

In the end your pithy comments aren’t going to convince me to start shoehorning blockchain into my day to day transactions — as much as I might long for a decentralized currency — and my fact-based analyses aren’t going to convince someone who has a financial or psychological interest in bitcoins or cryptocurrency or NFTs to abandon them. I suggest we just agree to disagree.

This is such a bad faith argument - you are transacting at any store in the fiat currency that store accepts and not crypto. That a service exists to seamlessly deduct an amount of crypto equivalent to that fiat is no more novel than one providing the same service between two fiat currencies, gold or Nuka cola caps.
